答案C fall off the bike意为:从自行车上跌下来,try to do sth.意为：尽力做某事.查看原帖

1.为什么不能选B或A.而答案是C呢.
Answer:
C."Though + 过去分词短语(非谓语形式)" 相当于"Although"引导的让步状语从句即:Though annoyed by her words
= Thought he was annoyed by her words.
而其它选项无此用法.
2.第一个空为什么填 despite ..despite of 才是加名词短语阿
Answer:
建议在分不清一个词能不能引导句子时,查一下字典看看其词性.
这里"despite"(介词)和"despite of"(介词短语) 意思都表"尽管",但不是连词无法引导句子,后面只接名词性成分 如名词、动名词、名词性从句,而不能接普通子句.(注:Despite of = In despite of = in spite of ,而其中"despite of" 是古用法,一般被视为鄙俗甚至不正确,现已很少用了)
注:
(1)Despite 作为介词虽不能引导句子,但因其介词属性后面可接名词从句
Despite what others say,I think he is very nice
不管别人怎么说,我仍认为他很好.
(2)"In spite of/Despite the fact that "用此结构到可引导句子,其中that引导同位语从句.但这样显得多么的复杂,还不如直接就用"although"连词直接去引导句子.
If you still feel confused,leave a message please

He tried to avoid answering my questions.
用法是try to do sth..试图去做什么
try doing sth是试试看的意思,多是用于提建议时用的.
例,sorry,he is not in.please try calling on his mobile..（请打他手机试试）.

push, free, cheer, sky

as

这里填 to catch
分析：try to do sth.尽力去做某事,努力做某事
try doing sth.尝试做某事,试着做某事
根据句子理解,他努力去追那只猫,却没能追到.try to do 比起try doing 付出更大的努力.

to catch

不能.even是甚至的意思,even if 才是尽管的意思,并且even的位置也不对

to explain
我怎么记得 try to 是尝试做 try doing 是努力做

he tried _to make me believe that he was my cousin
we don't want anybody _to(know)that we are here,

to open,to do
